In fact, I saw this in LINUX as early as I saw it. Later I also saw something similar in the MFC memory pool. I also wrote a similar small memory pool according to MFC, (MFC uses return this + 1) later, I saw a similar definition in Li xianjing's System Programmer growth plan, So I thought about it as a summary, the results showed that some cool people on the Internet had already summarized it very well, so it turned around. Thank you for your sharing

timer when matching. You can choose to interrupt the timer. 5. There are 3 timer 0 and 4 timer 1 correspond to the external output of the matching register.

The specific topic is this: Select n numbers from the 1--9, make up the number of n digits that are not duplicated, numbering from small to large, and when you enter any number m, you can find the number corresponding The number. such as n=3,m=213. Output: [123 (1), 132 (2), 213 (3), 231 (4), 312 (5), 321 (6)]--->x=2

0-1 Backpack:0-1 Backpack is the basis of knapsack problem, it derived from the knapsack problem roughly with the same idea.And since it belongs to the dynamic programming problem, its method lies in two steps: 1) define the state: Ans[i][t] represents the maximum value of t

First of all, I would like to thank my brother Xiaoxiao for helping you. Directly give the state transition equation: DP [I] [v] = max (DP [I-1] [v], DP [I-1] [V-Vol [I] + val [I]); Vol [I] is the volume of the I-th item, and Val is the value of the I-th item The equation means that when we consider the I items, there are only two options for I items: Put or not put, if not put the weight is the weight of
